Methods and systems to improve printed electrical components and for integration in circuits

ABSTRACT

Methods and systems to improve printed electrical components and for integration in circuits are disclosed. Passive components, e.g., capacitors, resistors and inductors, can be printed directly into a solid ceramic block using additive manufacturing. A grounded conductive plane or a conductive cage may be placed between adjacent electrical components, or around each component, to minimize unwanted parasitic effects in the circuits, such as, e.g., parasitic capacitance or parasitic inductance. Resistors may be printed in non-traditional shapes, for example, S-shape, smooth S-shape, U-shape, V-shape, Z-shape, zigzag-shape, and any other acceptable alternative configurations. The flexibility in shapes and sizes of the printed resistors allows optimal space usage of the ceramic block. The present invention also discloses an electrical component comprising combined predetermined values of capacitance, resistance and inductance. The integration and adjustability of a multi-property device can provide significant advantages in electronics manufacturing.

FIELD OF TECHNOLOGY

This disclosure relates generally to systems and methods to improve 3Dprinted electrical components and to integrate passive components inceramic chip package using the technique of drop-on-demand additiveprinting to deposit droplets of deposition material.

BACKGROUND

Photolithography has been a standard method of printed circuit board(PCB) and microprocessor fabrication. The process uses light to make theconductive paths of a PCB layer and the paths and electronic componentsin a silicon wafer of microprocessors.

The photolithography process involves light exposure through a mask toproject the image of a circuit, similar to a negative image in standardphotography. This process hardens a photo-resistive layer on the PCB orwafer. The hardened areas stay behind in the form of circuit paths ofprinted circuit boards (PCBs) and central processing units (CPUs).Unexposed areas are then dissolved away by a solution bath, such as anacid in wet methods or plasma-like oxygen ions in dry methods. A PCBmight have as many as twelve or more of these layers and a processor mayreach upwards of thirty or more, with some comprising metallicconductive layers and others insulating layers. Other steps includedeposition of conductive metallic elements.

Process shrinks, also known as die shrinks, are one of the main waysthat the miniaturization of electronic devices is made possible.Photolithography process shrinks involve miniaturization of allsemiconductor devices, particularly transistors. Processors made on asmaller scale generally mean more CPUs per wafer, either for cheaperproduction or a more complex and powerful processor in a given die size.Progress in miniaturization also fosters faster transistor switchingspeeds and lower power consumption, so long as there is not too muchcurrent leakage (which is one of the challenges that increase with thisprogress).

Photolithography is the selective removal of the oxide in a desired areaof a substrate. Thus, the areas over which diffusions are effective aredefined by the oxide layer with windows cut in it, through whichdiffusion can take place. The windows are produced by thephotolithographic process. This process is the means by whichmicroscopically small electronic circuits and devices can be produced onsilicon wafers resulting in billions of transistors on a 1 cm by 1 cmchip.

However, partly due to its lack of a high-temperature fusing processsuch as sintering, photolithography has had very limited value inintegrating relatively large capacitors, inductors, and resistors(“passive” components), forcing the continued use of discretecomponents. Manufacturing with discrete components is inherently moreexpensive, bulky, and wasteful of material than an integrated approach.Instead of trying to mount the larger components, onto a chip, or createthem with photolithography, a more efficient and effective system andmethod of integration is required.

SUMMARY

Disclosed are methods and systems to improve passive components and forintegration in ceramic chip package using 3D Printing. The methods andsystems disclosed herein may be implemented in any means for achievingvarious aspects. Other features will be apparent from the accompanyingdrawings and from the detailed description that follows.

Recently, it has become possible to create passive components usingadditive manufacturing, also known as 3D Printing, where ink jets oraerosol jets deposit materials such as ceramic slurry, conductive ink,ferrite paste, and carbon resistor paste. This is an inherently moreprecise and repeatable process than traditional methods, and produceshigher density components with less material waste. The materials justnamed can all be sintered at high temperature, so they are amenable tointegrated manufacture, which was previously not available inphotolithography. Sintering of ceramic powder material provides anadvantage over the prior art, such as, e.g., to produce an insulatorlayer that allows for an improvement in dielectric strength ofapproximately one thousand fold compared to previous procedures that canonly print capacitors comprising films, e.g., a plastic film insulatorlayer.

In one aspect, the present invention discloses a system and a method toprint electrical components, such as, e.g., multi-layer ceramiccapacitors, inductors and/or resistors, into the solid ceramic block ofan integrated circuit that is used in its packaging. Previously, passiveelectrical components have been mounted on the chip or created throughphotolithography, however, they can be created with high-temperaturesintering comprising exposed conductors designed to mate with the solderjoints (or other conductive scheme) on the chip. Sintering of ceramicpowder material provides an advantage over the prior art, such as, e.g.,to produce an insulator layer that allows for an improvement indielectric strength of approximately one thousand fold compared toprevious procedures that print capacitors comprising film, e.g., aplastic film insulator layer. The ceramic block may still providestiffness and strength, but in addition, it forms the matrix for thepassive components. A conductive plane may be printed in betweenadjacent electrical components, or a conductive cage may be printed toencapsulate each individual component to block unwanted parasiticeffects.

In another aspect, the present invention discloses a system and a methodfor improving printed electrical components, such as, e.g., capacitors,resistors, inductors and components with artificially combinedproperties of capacitance, resistance and inductance. In addition to theproperties being adjustable based on predetermined values, theintegration of a multi-property device can provide significantadvantages in electronics manufacturing as it allows for increasedfunctionality per unit volume and unit weight, and decreasing costthrough the reduction of manufacturing material.

DETAILED DESCRIPTION

Disclosed are systems and methods for improving printed electricalcomponents and for integrating in ceramic chip packages. Although thepresent embodiments have been described with reference to specificexample embodiments, it will be evident that various modifications andchanges may be made to these embodiments without departing from thebroader spirit and scope of the various embodiments. In addition, thecomponents shown in the figures, their connections, couples, andrelationships, and their functions, are meant to be exemplary only, andare not meant to limit the embodiments described herein.

Photolithography is the standard method of printed circuit board (PCB)and microprocessor fabrication. The process uses light to make theconductive paths of a PCB layer and the paths and electronic componentsin the silicon wafer of microprocessors. The ability to usephotolithography to “print” transistors and other electronic devices onsemiconductor material led to spectacular improvements in integratedcircuit density (and reduction in cost) over the last six decades. Thephotolithography technique has had very limited value in integratinghigh-specification capacitors, inductors, and resistors (“passive”components), forcing the continued use of discrete components.Manufacturing with discrete components is inherently more expensive,bulky, and wasteful of material than an integrated approach. The goal,therefore, is to find a practical and high-density way to produceintegrated passive components.

The photolithography process uses light to transfer a geometric patternfrom a photomask to a light-sensitive chemical called “photoresist”,onto a substrate. A series of chemical treatments then either engravesthe exposure pattern into, or enables deposition of a new material inthe desired pattern upon, the material underneath the photoresist.Photolithography shares some fundamental principles with photography inthat the pattern in the etching resist is created by exposing it tolight, either directly (without using a mask) or with a projected imageusing an optical mask.

FIG. 1 is a flowchart of an overview prior art process ofphotolithography used to create integrated chips. A single iteration ofphotolithography may combine several steps in sequence performed in acleanroom. Cleanrooms are typically automated and robotic wafer tracksystems are used to coordinate the process from beginning to end.

Operation 110 prepares the substrate water. The wafer may be initiallyheated to a temperature sufficient to drive off any moisture on wafersurface, such as, e.g., 150° C. for ten minutes. Operation 120 applies aphotoresist, a light-sensitive liquid, to the center of an oxidizedsilicon wafer. The wafer may be spun rapidly to produce a uniform layer.Operation 130 aligns a photomask. The coated wafer is now placed in anapparatus called a mask aligner in very close proximity to thephotomask. The photomask has a photographic emulsion or thin film metal(generally chromium) pattern on one side. The pattern has clear andopaque areas. Operation 140 exposes the silicon wafer to UV light. Ahighly collimated ultraviolet (UV) light may be turned on and the areasof the silicon wafer that are not covered by the photomask are exposedto ultraviolet radiation. Positive photoresist, the most common type,becomes soluble in the developer when exposed; with negativephotoresist, unexposed regions are soluble in the developer.

Operation 150 develops and removes photoresist exposed to UV light. Inthe event that a negative photoresist is used, the areas of thephotoresist that are exposed to the ultraviolet radiation becomepolymerized. The resisting photoresist pattern after the developmentprocess will therefore be a replication of the photomask pattern, withthe clear areas on the photomask corresponding to the areas where thephotoresist remains on the wafers. An opposite type of process occurswith positive photoresist. After development and rinsing, the wafers areusually given a “post-bake” in an oven at a temperature of about 150° C.for about 30 to 60 minutes to toughen further the remaining resist onthe wafer. The resulting wafer is then “hard-baked”, which may solidifythe remaining photoresist, to make a more durable protective layer infuture ion implantation, wet chemical etching, or plasma etching.Operation 160 etches the exposed oxide layer. A liquid (“wet”) or plasma(“dry”) chemical agent removes the uppermost layer of the substrate inthe areas that are not protected by photoresist. The exposedsemiconductor underneath are ready for impurity diffusion. Operation 170removes the remaining photoresist.

FIG. 2 is a typical surface-mount processor chip with discrete passivecomponents. The dark square in the center is a processor chip made froma semiconductor and encased in ceramic (the “chip package”) thatprotects the chip from moisture. Surrounding that chip are two-electrodedevices, such as, e.g., mostly multi-layer ceramic capacitors (MLCCs).

FIG. 3 shows the various sizes of discrete multilayer ceramiccapacitors. MLCCs are currently manufactured as discrete components in awide range of sizes and specifications. Even the smallest MLCC ingeneral use may be millions of times larger than the transistors inintegrated devices. That is one reason they are difficult to integratelithographically. Another reason is that the ceramic material in an MLCCis made with a high-temperature process that would destroy the devicesthat are created lithographically. Therefore, efforts to integratepassive components have, to date, focused on placing them on thesemiconductor wafer prior to packaging.

Plastic or ceramic packaging involves mounting a die, connecting diepads to the pins on the package, and sealing the die. Tiny wires areused to connect the pads to the pins. Traditionally, these wirescomprise gold leading to a lead frame of solder-plated copper.

FIG. 4 is a typical packaging of an integrated chip circuit chip,according to at least one embodiment. A typical “flip chip” packagingstyle is shown. Board 400 may be a multilayer printed circuit boardsimilar to that shown holding the components in FIG. 2. Discretecomponents such as, e.g., MLCCs, are mounted separately throughconductive paths printed on board 400. Ceramic base 402 may comprise anordinary ceramic material, formed by high temperature sintering; itprovides mechanical strength and stiffness, since any flexing mightbreak electrical connections. Thermal grease 404 may be applied betweenlid 406 and circuit die 408. Lid 406 may encapsulate die 408 to protectand insulate die 408 from the outside environment. Board 400 and die 408may both be coupled to ceramic base 402 by an array of solder bump 410.

Recently, it has become possible to create passive components usingadditive manufacturing, also known as 3D Printing, where ink jets oraerosol jets deposit materials such as ceramic slurry, conductive ink,ferrite paste, and carbon resistor paste. This is an inherently moreprecise and repeatable process than traditional methods, and produceshigher density components with less material waste. The materials justnamed can all be sintered at high temperature, so they are amenable tointegrated manufacture, which was previously not available inphotolithography. Sintering of ceramic powder material provides anadvantage over the prior art, such as, e.g., to produce an insulatorlayer that allows for an improvement in dielectric strength ofapproximately one thousand fold compared to previous procedures that canonly print capacitors comprising films, e.g., a plastic film insulatorlayer.

FIG. 5 is a system of a drop-on-demand type additive printer that may beused to implement one or more embodiments of the present invention. Aslurry jet 500 may be dispensed from a nozzle 504 having an orificecomprising an opening, and may be raster or vector scanned on track 506by a carriage 508 driven by drive unit 510 over a surface 512 or on topof an already formed powder bed to define a new layer. Pressure may beused to force the slurry out of the nozzle and into a continuous streamof slurry jet 500 and/or as droplet 502, which may be defined as abreakup of the flow. A layer surface height measurement unit, such as,e.g., a laser rangefinder may be used to receive an input signal tocontrol the height of the surface that is formed by varying the deliveryof slurry.

A typical implementation of an additive manufacturing process beginswith defining a three-dimensional geometry of the product usingcomputer-aided design (CAD) software. This CAD data is then processedwith software that slices the model into a plurality of thin layers,which are essentially two-dimensional. A physical part is then createdby the successive printing of these layers to recreate the desiredgeometry. This process is repeated until all the layers have beenprinted. Typically, the resulting part is a “green” part, which may bean unfinished product that can undergo further processing, e.g.,sintering. The green part may be dense and substantially non-porous. Insome circumstances, the part may be a final part.

FIG. 6 is a flow diagram of a method of an additive printing processthat may be implemented with one or more embodiments of the presentinvention. Operation 610 defines a final product's three-dimensionalgeometry using CAD software. Operation 620 deposits layers of slurrycomprising powder material onto a surface or on top of a powder bed,which then slip-casts to make a new layer. As the slurry deposits ineach two dimensional layer, the printer may select insulator and/orconductor as the material type, in separate passes or as a combinedpass. The slurry may be deposited in any suitable manner, includingdepositing in separate, distinct lines, e.g., by raster or vectorscanning, by a plurality of simultaneous jets that coalesce before theliquid slip-casts into the bed, or by individual drops. The deposit ofslurry drops may be individually controlled, thereby generating aregular surface for each layer. Operation 630 dries any liquid from thepowder bed, e.g., infrared flash-dry, after deposition of each layer.Operation 640 repeats operations 620 and 630 until a green part isformed. Operation 650 sinters the green part to form a final product.Sintering is a solid-state diffusion process that may be enhanced byincreasing the surface area to volume ratio of the powder in any greenpart that is subsequently sintered.

In at least one embodiment, the present invention discloses a system anda method to 3D print electrical components, such as, e.g., multilayerceramic capacitors, inductors and/or resistors, into the solid ceramicblock of an integrated circuit that is used in its packaging.Previously, passive electrical components have been mounted on the chipor created through photolithography, however, they can be created withhigh-temperature sintering comprising exposed conductors designed tomate with the solder joints (or other conductive scheme) on the chip.Sintering of ceramic powder material provides an advantage over theprior art, such as, e.g., to produce an insulator layer that allows foran improvement in dielectric strength of approximately one thousand foldcompared to previous procedures that print capacitors comprising film,e.g., a plastic film insulator layer. The ceramic block may stillprovide stiffness and strength, but in addition, it forms the matrix forthe passive components.

FIG. 7 is a schematic of an integration of passive components in aceramic part of a chip packaging, according to at least one embodiment.In the present figure, depth dimension, component interconnects,components to PCB connections, and conductive shieldings were omittedfor clarity. This figure illustrates an inventive concept of the presentdisclosure, as applied to the form of packaging shown in FIG. 4. Ceramicmatrix 700 may comprise resistor 702 represented by a dark rectangle,inductor 704 represented by a helical shape (with or without a ferritecore), and capacitor 706 represented by a multilayer zig-zag shape. Theyare shown in different proportions and in different angles to emphasizethat the orientation and form factors of the passive elements are highlyflexible and not constrained to being axis-aligned. Their individualgeometries can be curved, warped, zig-zag or any other shape. Oneadvantage of being able to angle the components is that it providescontrol of the parasitic effects the components have on each other andon the devices within the chip.

It is also possible to 3D print an air gap between devices (permittivityof approximately 1.0), up to predetermined minimal strength andstiffness threshold requirements to sufficiently support the chipsubstrate. For aerosol and inkjet 3D printers, overhang may not bepossible, so any air gaps must be placed at the top of the device in itsconstruction orientation. The device can be placed at any angle aftercompletion of manufacture.

As part of the design of any such 3D-printed ceramic matrix, a computermodeling program such as, e.g., COMSOL, may be employed to optimize thelayout and check for cross-interference between elements. It isimportant to prevent effects such as resonance or parasitic effects thatcan spoil the behavior of the chip or force the use of lower-speed chipoperation.

FIG. 8 is a flow diagram of a method of an additive printing processthat may be implemented with one or more embodiments of the presentinvention. Operation 810 optimizes a circuit's component layout usingCAD software. An algorithm of a computing device comprising a memory anda processor may be used to determine space, position and orientation ofeach individual component of an integrated chip during a planning phaseprior to construction of the chip. Operation 820 deposits layers ofslurry comprising powder material onto a surface or on top of a powderbed, which then slip-casts to make a new layer. As the slurry depositsin each two dimensional layer, the printer may select insulator and/orconductor as the material type, in separate passes or as a combinedpass. The slurry may be deposited in any suitable manner, includingdepositing in separate, distinct lines, e.g., by raster or vectorscanning, by a plurality of simultaneous jets that coalesce before theliquid slip-casts into the bed, or by individual drops. The deposit ofslurry drops may be individually controlled, thereby generating aregular surface for each layer. Operation 830 dries any liquid from thepowder bed, e.g., infrared flash-dry, after deposition of each layer.Operation 840 repeats operations 820 and 830 until a green part isformed. Operation 850 sinters the green part to form a final product.Sintering is a solid-state diffusion process that may be enhanced byincreasing the surface area to volume ratio of the powder in any greenpart that is subsequently sintered.

One challenge in integrated circuit packaging is to avoid parasiticcapacitance and parasitic inductance. In real electrical circuits,parasitic capacitance and parasitic inductance are unavoidable andusually unwanted effects that exists between the parts of electroniccomponents or circuits simply because of their proximity to each other.One way to minimize parasitic effects is to use a “Faraday cage” (orFaraday shield), which is simply a grounded conductor placed between thecoupling source and affected component. By precise printing of aconductive material around the electrical component in the ceramic blockusing 3D Printing technique and connecting it to a ground, a Faradaycage is formed and the parasitic effect is greatly reduced.

FIGS. 9A-B is a circuit showing a high-frequency noise source coupled toa system impedance through a stray capacitance, according to at leastone embodiment. In FIG. 9A, parasitic capacitance 900 may be caused bythe close proximity of noise source 902 and circuit impedance 904. Ifthere is little or no control over source 902 or the location ofimpedance 904, the next best solution may be to interpose a Faradayshield. FIG. 9B shows Faraday shield 906 interrupting the couplingelectric field. Shield 906 causes noise 902 and coupling currents toreturn to their source without flowing through the circuit impedance904.

Inductive coupling effect is one example of parasitic effects, andrefers to the transfer of energy from one circuit component to anotherthrough a shared magnetic field when these components are placed inclose proximity. A change in current flow through one device inducesvoltage change and current flow in the other device. Inductive couplingis an unwanted parasitic effect that affects the performance of thesemiconductor devices. The effect can be mitigated by 3D printing aconductive plane or capsule, e.g., as a Faraday shield or a Faradaycage, between the adjacent devices, or around the individual device, andconnecting the conductive plane or capsule to a ground. This approachallows passive components to be printed at high density in a way that isdifficult to achieve without additive manufacturing. In a system whichpassive components are added as discrete components, designing acustom-shaped shielding around each component can greatly increasemanufacturing cost. However, with 3D Printing technique, manufacturing aconductor plane or capsule for custom-shaped shielding is just as easyas printing other electrical components.

FIGS. 10A-B illustrate embedded conductors of an integrated circuit thatexhibit unintended effects, according to at least one embodiment. Theconductors may be 3D printed into the ceramic block and may experiencethe effect shown in FIG. 10A. Conductor I 1000 may be live with current1002 flowing through, while conductor II 1004, such as from a separatedevice or the same device, may be at rest. The close proximity ofconductor I 1000 and conductor II 1004 may create induced voltage flow1006 through conductor II 1004 due to magnetic flux 1006 of conductor I1000. The magnetic flux 1006 of conductor I 1000 may influence (induct)conductor II 1004 through contact with a common magnetic flux 1008shared between conductor I 1000 and conductor II 1004. In FIG. 10B, byusing a system and a method of the present invention of additivemanufacturing, a conductive plane 1010 may be printed between conductorI 1000 and conductor II 1004. The precision of the system and the methodallows for the thinnest amount of conductive material to be used toprint the conductive plane that is required to keep magnetic flux 1006of conductor I 1000 from inducing conductor II 1004, such as, e.g., avoxel of material thick. The minimal material used allows for higherdensity printing of the grounded conductive plates, while keeping costslow or constant. Conductive plane 1010 may be connected to a ground.

In the present invention, the embedded 3D-printed conductors mayexperience inductive coupling effects because the electrical componentsare close to each other.

With the ability to print very thin layers of the grounded conductiveplate or capsule for every electrical component, the parasitic effectscan be greatly reduced while allowing electric components in the ceramicblock to be printed at a very high density.

FIG. 11 is a schematic diagram of an integrated circuit, wherein aFaraday cage is positioned around each individual component, accordingto at least one embodiment. Faraday cage 1100 may be a groundedconductor that encapsulates individual embedded devices to blockunwanted flux. The encapsulation may take the general shape of thedevice it encapsulates, and may be slightly larger in a manner to notmake physical contact with the device. The precision of the system andthe method allows for the thinnest amount of conductive material to beused to print the cage that is required to minimize parasitic effects,such as, e.g., a voxel of material thick. The encapsulation may compriseone or more hole 1102 to allow passage of electrodes through smallopenings. For example, hole 1102 may comprise a predetermined minimumdiameter to keep the Faraday cage 1100 effective, while does not makecontact with another conductive material. The encapsulation would reduceunwanted effects, such as, e.g., parasitic effects, such that thedevices can be placed more closely to one another without interference,such as, e.g., a distance of less than 10 microns.

A Faraday cage may be grounded by a connection to a solder bump 1104,which is subsequently grounded to a printed circuit board 1106, as shownin the figure. However, it may be possible for lid 1106 to be grounded,and therefore grounding of the capsules to lid 1106 may be beneficial.Additionally, there may be more than one ground in an effort to controlsignal noise.

A ceramic integrated-circuit package may comprise a small, square,conducting lid soldered onto a metallized rim on the ceramic packagetop. The metallized rim may be connected to one of the corner pins ofthe package, or it may be left unconnected. Most logic circuits have aground pin at one of the package corners, and therefore the lid isgrounded. But many analog circuits do not have a ground pin at a packagecorner, and the lid is left floating. Traditionally, a wire may besoldered to the lid (this will not damage the device, as the chip isthermally and electrically isolated from the lid). If soldering to thelid is unacceptable, a grounded phosphor-bronze clip may be used to makethe ground connection, or conductive paint can be used to connect thelid to the ground pin. The additive manufacturing technique of thepresent invention may allow precise adjusting of Faraday shielding whichmay in turn reduce or minimize electromagnetic leaks from the lid.

FIG. 12 illustrates a ceramic integrated circuit package comprising agrounded lid, according to at least one embodiment. The system andmethod of the present invention may print a ceramic chip package 1200comprising lid 1202, which may be a grounded conductor. In this case, acomponent's Faraday cage may be connected to lid 1202 instead of asolder bump.

FIG. 13 is a flow diagram of a method of an additive printing processthat may be implemented with one or more embodiments of the presentinvention. Operation 1310 optimizes a circuit's component layout usingCAD software. An algorithm of a computing device comprising a memory anda processor may be used to determine space, position and orientation ofeach individual component of an integrated chip during a planning phaseprior to construction of the chip. Operation 1320 determinesconfiguration of Faraday shielding for all components such as, e.g.,capacitors, inductors, and resistors. The algorithm may also determineFaraday shielding in order to minimize electromagnetic leaks from thelid.

In at least one embodiment, the present invention also discloses asystem and a method for improving printed electrical components, suchas, e.g., capacitors, resistors, inductors and components withartificially combined properties of capacitance, resistance andinductance. In addition to the properties being adjustable based onpredetermined values, the integration of a multi-property device canprovide significant advantages in electronics manufacturing as it allowsfor increased functionality per unit volume and unit weight, anddecreasing cost through the reduction of manufacturing material. Otherdevices are 3D-printable with the same set of materials andtechnologies. For example, by printing two helices of different pitchsharing a common core, a voltage transformer is obtained.

In at least one embodiment, the present invention discloses a system anda method to improve a resistor through 3D Printing. Carbon paste can beused to print resistors. Mass-manufactured resistors may be subjected tohigh amounts of variation in their resistivity, e.g., ±20%, thoughtechniques such as an additional step of laser trimming can reducevariation below 1%, as well as restriction to specific standard ohmvalues (powers of ten times 10, 15, 22, 33, 47, or 68). With 3Dprinting, the geometry is so precisely controllable and repeatable thatvariation can be far lower in a single manufacturing step compared tothe use of trimming. They can also be made to any value, economically,without adherence to a preferred number series.

Furthermore, the ability to vary both the thickness (cross sectionalarea) and the length of a resistor provides the ability to select thewattage rating of a resistor and not just the resistance value. Highercross section increases the wattage rating, the amount of power aresistor can dissipate before it fails. Higher cross section alsoreduces resistance, which is compensated by making the resistor longer.Other variations in shape parameters are also possible, such as theeccentricity of the cross section. For closest-possible packing ofcomponents, it may be desirable to allow resistors to be unusual,complex geometries that fill in the spaces between inductors andcapacitors, since resistors are the most forgiving of being non-idealshapes of the three types of passive component. An algorithm may be usedto find the most effective parameters in a resistor design.

FIGS. 14A-G show alternative configurations for resistor shape allowedby the additive manufacturing technique of the present invention,according to some embodiments. Individual components of an integratedcircuit may be positioned on and within the circuit first whileremaining spaces are used to position resistors of different geometries,such as varying shapes and sizes. The placement of the resistors afterall of the other electrical components on the integrated circuit allowsfor optimized configurations of the integrated circuit, such as, e.g.,minimizing (or maximizing) parasitic effects, without the need forsignificant consideration of the space remaining.

FIG. 14A is a Z-shape resistor comprising three linear segments joinedtogether by two vertices, resembling the letter Z. The configuration ofthe Z-shape resistor may be altered by adjustment of any individualinner angle 1400 or outer angle 1402, both of which produce opposingeffects on its shape. The Z-shape resistor may also vary in individualsegment lengths and/or number of segments; however, each vertex may joinno more than two segments. FIG. 14B is a U-shape resistor comprising asingle segment that may be bent into a semi- or nearly-closed-circle. Onthe other hand, the segment may be divided into three individual piecesjoined at two vertices in such a manner where the resistor resembles theshape of a box with an open lid or top. The U-shape resistor may alsocomprise irregular bends and/or curves that may detract the resistorfrom its original U-shape, such as one of the ends of the resistor maybend and/or curve inward and/or outward to avoid making contact withanother component on the integrated circuit.

FIG. 14C is a V-shape resistor comprising two segments joined at asingle vertex that resembles the letter V. The segments may vary inlength or may be of equal length. The angle formed by the two segmentsmay be of any value, whether forming an acute, obtuse, or right angle.Each segment may also comprise irregular bends and/or curves that maydetract it from its original V-shape, such as one of the ends of theresistor may bend and/or curve inward and or outward to avoid makingcontact with a component on the integrated circuit. FIG. 14D is acrescent-shape resistor comprising or a single segment that is bent intoa curve. The leads in this figure are illustrated only by way of exampleto reflect that the resistor may comprise leads protruding from bothends, or comprise the integrated surface-mount leads illustrated in thealternative figures of the set. Additionally, the single segment may bedivided into multiple segments joined by vertices. Typically, in thissituation, there would be one less vertex per amount of segments aboveone, e.g., six segments joined at five vertices to form acrescent/semicircular-shape resistor.

FIG. 14E is an S-shape resistor comprising five segments joined togetherat four vertices that resembles the letter S. The four vertices may formright angles (90-degrees). The resistor may be modified into any numberof segments, with typically one less vertex per amount of segments.Additionally, the S-shape resistor may be smooth and does not comprise avertex as shown in FIG. 14F. FIG. 14G is a zigzag-shape resistor, whichis another configuration for the S-shape resistor. Contrary to theS-shape resistor, the zigzag-shape resistor's five segments form acuteangles (>90-degrees) instead of the right angles seen in the S-shaperesistor of FIG. 14E. However, its similarities are that it may be ofany number of segments with one less vertex than the amount of segmentspresent, and that a single vertex joins no more than two segments.

FIG. 15 is a schematic diagram of an integrated circuit comprisingvarious shapes of resistors, according to at least one embodiment.Ceramic matric 1500 may comprise a U-shape resistor 1502 positionedbelow an inductor such that the U-shape resistor 1502's opening facesupward and the inductor is positioned within the cradle of the U-shapewithout making physical contact. A Z-shape resistor 1504 and a V-shaperesistor 1506 may also be positioned in a manner to optimize spaceefficiency of the circuit while minimizing adverse effects. The presentinvention is not limited to these shapes (or sizes). Any geometry may beachieved through a method of the present invention.

Alternative configurations for resistor shape can be achieved by theprinting technique of the present invention, drop-on-demand additivemanufacturing. Individual components of an integrated circuit may bepositioned on and within the circuit first while utilizing any remainingspace to position resistors of different geometries, such as varyingshape and size. The placement of the resistors after all of the otherelectrical components on the integrated circuit allows for optimizedconfigurations of the integrated circuit, such as, e.g., minimizing (ormaximizing) parasitic effects, without the need for significantconsideration of the space remaining. In addition, each component may beencapsulated within a conductive layer to form a Faraday shield forminimizing parasitic effects.

FIG. 16 is a flow diagram of a method of an additive printing processthat may be implemented with one or more embodiments of the presentinvention. Operation 1610 optimizes a circuit's component layout usingCAD software. An algorithm of a computing device comprising a memory anda processor may be used to determine space, position and orientation ofeach individual component of an integrated chip during a planning phaseprior to construction of the chip. Operation 1620 determines placementand configuration of resistors after all other components. The resistorsmay be optimized to comprise any shape and size to meet a predeterminedspecification, and may be positioned in such as manner to utilizeremaining space of the ceramic package. Operation 1630 deposits layersof slurry comprising powder material onto a surface or on top of apowder bed, which then slip-casts to make a new layer. As the slurrydeposits in each two dimensional layer, the printer may select insulatorand/or conductor as the material type, in separate passes or as acombined pass. The slurry may be deposited in any suitable manner,including depositing in separate, distinct lines, e.g., by raster orvector scanning, by a plurality of simultaneous jets that coalescebefore the liquid slip-casts into the bed, or by individual drops. Thedeposit of slurry drops may be individually controlled, therebygenerating a regular surface for each layer. Operation 1640 dries anyliquid from the powder bed, e.g., infrared flash-dry, after depositionof each layer. Operation 1650 repeats operations 1630 and 1640 until agreen part is formed. Operation 1660 sinters the green part to form afinal product. Sintering is a solid-state diffusion process that may beenhanced by increasing the surface area to volume ratio of the powder inany green part that is subsequently sintered.

In at least one embodiment, the present invention discloses a system anda method to improve an inductor through 3D Printing. An inductor usuallyconsists of a coil of conducting material, typically insulated copperwire, wrapped around a core made of plastic or ferromagnetic material.The high permeability of the ferromagnetic core increases the magneticfield, therefore increasing the inductance. Most inductors are large,which prevents them from being integrated in semiconductor chips. Smallinductors can be printed on a chip with photolithography using the sameprocesses that make transistors. They are typically made in the form ofa flat spiral with the conductive material required by the chip. Theconductive material can be combined with ferromagnetic material toincrease the inductance per unit area.

With 3D printing, there is no restriction to flat geometries, so ahigher inductance can be achieved (per unit volume instead of per unitarea). For instance, it is possible to print a helical coil, or atoroidal coil, and the core could be omitted (when linear behavior isdesired) or 3D printed with a ferrite for much higher inductance. Toreduce parasitic capacitance in an inductor, geometric techniques suchas “basket-weave coils” or “spider web coils” have been traditionallyused, at increased manufacturing cost. With 3D printed inductors, thereis no additional manufacturing cost for the use of sophisticatedgeometries.

In at least one embodiment, the present invention discloses a system anda method to improve a capacitor. MLCCs made of alternating layers offerroelectric (high-K) dielectric and conductor can be embedded in thelow-K dielectric matrix material. The use of low-K material betweencapacitors, in combination with grounded conductive Faraday cagesbetween components as needed, means that separate capacitors can thus beplaced in close proximity without creating parasitic effects.

A ceramic slurry can be made with barium titanate (BaTiO₃) exhibits theferroelectric effect, giving permittivities thousands of times that of avacuum; it therefore can be used to make high-performance, high-densitycapacitors. A slurry made with alumina, on the other hand, has lowpermittivity and therefore is less likely to create unwanted capacitancebetween nearby conductors. As an example, MLCCs have been built withdoped barium titanate materials that exhibit permittivity as high as6500; alumina, on the other hand, has a permittivity around 10, almostthree orders of magnitude lower.

FIG. 17 is a flow diagram of a method of additive manufacturing that maybe implemented in one or more embodiments of the present invention.Operation 1710 provides a support over a selected area. Operation 1720deposits liquid slurry to form a first layer comprising conductivemetal, such as, e.g., copper, nickel, silver, palladium, gold, and/orplatinum. The slurry may be deposited as continuous parallel streams, oras individually controlled droplets, thereby generating a regularsurface for each layer. Operation 1730 deposits liquid slurry to form asecond layer comprising dielectric or ceramic material, such as, e.g.,barium titanate. Operation 1740 deposits liquid slurry to form a thirdlayer. The third layer may comprise the same material as the firstlayer. In some embodiments, operation 1720 and operation 1730sequentially repeat until a predetermined amount of alternating layersof conductor and dielectric material is achieved. Operation 1750 driesthe powder bed by flash drying, e.g., infrared heating. Operation 1760sinters the layers to form a final product.

FIG. 18 is a flow diagram of another method of additive manufacturingthat may be implemented in one or more embodiments of the presentinvention. Operation 1810 deposits a first conductive layer onto asurface. Operation 1820 deposits a dielectric layer on a top surface ofthe first conductive layer. Operation 1830 deposits a second conductivelayer onto a top surface of the dielectric layer. Optionally, operation1840 repeats operation 1820 and operation 1830 successively andsequentially such that the conductive layers and the dielectric layersalternate, and the conductive layers are disposed at both the bottomlayer and the top layer, although in practice, the MLCCs may bemanufactured with dielectric layers disposed at both the bottom layerand the top layer. The aforementioned steps may produce a ceramiccapacitor comprising a first conductive layer formed on a surface of adielectric layer, and a second conductive layer formed on the opposingsurface of the dielectric layer.

In at least one embodiment, the present invention discloses a system anda method of an adjustable multi-property device. In general, each typeof passive component has some amount of behavior like that of the othertwo. Resistors have some inductance and capacitance; inductors haveresistance and capacitance; capacitors have some resistance andinductance. They are not “ideal” devices. When circuits are designed asidealized passive components in series and parallel, 3D printing enablescreation of devices that can provide a single device that has the samefunction as a combination of ideal devices on a circuit diagram, therebyincreasing functionality per unit volume and unit weight and decreasingcost through reduction of material needed for manufacture.

An RLC circuit is an electrical circuit comprising a resistor, aninductor, and a capacitor, connected in series or in parallel. The RLCpart of the name is due to those letters being the usual electricalsymbols for resistance, inductance and capacitance respectively. Someresistance is unavoidable in real circuits, even if a resistor is notspecifically included as a component. A pure LC circuit is an ideal thatexists only in theory.

FIG. 19 is an example RLC circuit comprising a resistor, an inductor,and a capacitor, according to at least one embodiment. There are manyapplications for this circuit, such as for tuning radio receivers ortelevision sets, where they are used to select a narrow range offrequencies from the ambient radio waves. An RLC circuit can be used asa band-pass filter, band-stop filter, low-pass filter or high-passfilter. The tuning application, for instance, is an example of band-passfiltering. The three circuit elements can be combined in a number ofdifferent topologies. All three elements in series or all three elementsin parallel are the simplest in concept and the most straightforward toanalyze; however, other arrangements may be used.

The present invention discloses a system and a method of artificiallycombining RLC properties in a single component. 3D Printing enablescreation of a single device that comprise the same properties as acombination of ideal devices on a circuit diagram, thereby increasingfunctionality per unit volume and unit weight and decreasing costthrough reduction of material needed for manufacture. The properties maybe adjustable and based on the application that it is intended. Thereare two approaches that can create such “in-between” componentproperties: intermediate shapes and intermediate ink or aerosolmixtures.

FIG. 20 illustrates a 3D-printable component with both inductance andcapacitance through an intermediate shape and ink, according to at oneembodiment. An intermediate shape may be a shape comprising acombination of shapes typically associated with particular electricalcomponents, such as, e.g., a combination of a helical coil shape of aninductor and a cylindrical shape housing of a capacitor. An intermediateink may be a mixture or gradient of conductor material and insulatormaterial may be used to achieve a predetermined property orspecification of the component.

Helical coil 1800 may comprise conductive material encased incylindrical housing 1802 comprising high-K dielectric, such as, e.g.,barium titanate. As shown, this is a four-electrode device, withdifferent inductance-capacitor properties depending on which electrodepair is used as the component electrodes; however, any number ofelectrodes can be employed, such as, e.g., two or six or eight.

In order to appreciate how intermediate ink could be used, consider anideal MLCC, with layers of perfect conductor separated by layers ofperfect insulator. Actual MLCCs have a small amount of resistance incharging or discharging, since the conductor is not ideal. This iscalled Equivalent Series Resistance (ESR) because it is like connectinga resistor in series to the capacitor. Conversely, actual MLCCinsulators do not have infinite resistance; there is always some currentleakage, equivalent to Equivalent Parallel Resistance (EPR). Both kindsof resistance are useful in circuits, and presently circuits simplycombine a near-ideal capacitor with a near-ideal resistor in eitherparallel or series. But 3D printing allows any combination of ESR andEPR with the capacitor for almost the same device volume as thecapacitor alone. Adding resistor ink (for example, nanoscale carbon insuspension) to the conductor ink (for example, silver nanoparticles)will increase ESR. Adding resistor ink to the insulator ink (forexample, barium titanate) will decrease EPR. In other words, a varyinggradient of conductor material and insulator material may be used toachieve a predetermined property or specification of the component. Asimilar approach applies to inductors.

FIG. 21 is a flow diagram of a method of an additive printing processthat may be implemented with one or more embodiments of the presentinvention. Operation 2110 defines a final product's three-dimensionalgeometry using CAD software. Operation 2120 deposits layers of slurrycomprising powder material onto a surface or on top of a powder bed,which then slip-casts to make a new layer. As the slurry deposits ineach two dimensional layer, the printer may select insulator and/orconductor as the material type, in separate passes or as a combinedpass.

A capacitor, a resistor, an inductor, and/or a multi-property device maybe printed into a ceramic package of an integrated circuit. Depending onthe shape and configuration of the components, each layer will printportions of the capacitor, resistor and/or inductor using materials suchas, e.g., carbon and ferrite pastes, conductive ink, ceramic and metalslurry. Intermediate ink such as a gradient mixture of conductormaterial and insulator materials may be used to control, adjust, andultimately achieve a desired property or specification of the component.For example, adding resistor ink, e.g., nanoscale carbon in suspension,to the conductor ink, e.g., silver nanoparticles, will increase ESR.Adding resistor ink to the insulator ink, e.g., barium titanate, willdecrease EPR. In other words, a varying gradient of conductor materialand insulator material may be used to achieve a predetermined propertyor specification for the component. In addition, a conductive plane maybe printed between adjacent components, or a conductive cage may beprinted around each individual components. The conductive plane and/orthe conductive cage may be grounded.

The slurry may be deposited in any suitable manner, including depositingin separate, distinct lines, e.g., by raster or vector scanning, by aplurality of simultaneous jets that coalesce before the liquidslip-casts into the bed, or by individual drops. The deposit of slurrydrops may be individually controlled, thereby generating a regularsurface for each layer. Operation 2130 dries any liquid from the powderbed, e.g., infrared flash-dry, after deposition of each layer. Operation2140 repeats operations 2120 and 2130 until a green part is formed.Operation 2150 sinters the green part to form a final product. Sinteringis a solid-state diffusion process that may be enhanced by increasingthe surface area to volume ratio of the powder in any green part that issubsequently sintered.
